a) Same as Fig. 1a but for the source SS3. The contour levels start at 0.0 K km s-1 and increments are 2.0 K km s-1. b) NH3(1, 1) radial velocity (color map) structure. The velocity field is shown after subtracting the mean radial velocity ⟨ VLSR ⟩ = 7.542 km s-1. The white crosses mark offsets where the splitting of the NH3 profiles is detected (see Fig. B.8). The mean radial velocities of the components A and B are ⟨ VA ⟩ = 7.865 ± 0.005 km s-1 and ⟨ VB ⟩ = 6.856 ± 0.010 km s-1. The intensity peaks are labeled as in Table 1. c) NH3 intensity map as in panel a) and positions of the MAMBO millimeter sources taken from Table 1 in Maury et al. (2011). Red and yellow open circles mark starless and YSO candidates, respectively.
